What is Smart Communications’ BIG and FREE secret?

Facebooks fans of Smart Communications are treated with a mystery that’s driving them insane. Smart is coming up with a promo at the end of this month that’s supposed to be BIG, FREE and for 18 and Up only.

Now what is it really? Smart says fans of their Facebook page will get first dibs on what the promo is all about. Is Smart really coming up with something that’s for adults only hence the 18 and up caption? Or are all of these smokescreen to get a lot of people like their Facebook page?
